comment Is StackExchange.com Addiction Dangerous?
dangerous how? spending too much time on SE may be detrimental to your social life. but you're also helping a lot of SE consumers. what exactly do you want to know? and can you form the question in such a way that requires a concrete, objective answer? otherwise i vote to close.

comment When one activity makes you less distracted doing another activity?
as is, i think this question is too broad. yes, 'things' can help people focus on other 'things'. in the psych literature, it's called attention. it's worth noting that caffeine (in tea) can cause increased attention. so perhaps that plays a role in your case. (in fact, this may be a viable question if you limit this to possible effects of tea on attention)

@Pavel by computation i meant calculation (as opposed to recall), whose meaning i inferred from fgregg's question.

comment Is it possible to distinguish recall and calculation?
No, latency is not necessarily the only way, just the most obvious. Imaging might help-- as I mentioned, there are ACT-R models of arithmetic, and a corresponding ACT-R "brain hypothesis", which translates a model into fMRI predictions, so you could use that, or another free-standing experiment. not sure if the temporal resolution of fMRI is good enough or not. you could also look at error rate, if there's some reason to believe certain operations are more error-prone than others. there are probably other possibilities as well...

comment Can experience alter one's preferences for beauty?
sorry, i did not see the tag... the title is a bit misleading though, i think. Perhaps something like 'By what mechanism does experience alter perceptions of beauty?' or something

I told her that her experiences with a previous boyfriend [...] had radically changed her views... Doesn't that answer your question right there? You're accusing your friend of the very thing you're unsure about.
